Abstract: PROBLEM TO BE SOLVED: To prevent wasteful ink consumption and poor image formation by a method wherein the number of ink delivery times is weighted by multiplying with the predetermined coefficient corresponding to a head temperature so as to control a suction device for forcibly sucking ink from ink delivery ports and a recording head based on the resultant weighted number of times. SOLUTION: The first forced suction performed is executed after the mounting of a carriage onto a recording head and before the starting of printing at the step S1. At this time, an ink discharging number memory is cleared at the step S2. Next, when printing is started at the step S3, a head temperature is measured with a head temperature sensor at the step S4. Ink discharging number is counted on the basis of printing signal at the step S5. Further, the ink discharging number is weighted by multiplying the ink discharging number with the predetermined coefficient corresponding to the head temperature at the step S6. The resultant ink discharging number is added to the ink discharging number memory at the step S7.  When the sum of the ink discharging number reaches 13×10<7> , the recording head is moved above a suction device so as to forcibly such ink from ink delivery ports by means of the suction device.

Title: Magnetic information reproducer
Inventor: KOMIYAMA KOUZOU
IPC: G11B5/02
Filed: 1984-06-12
Abstract: PURPOSE:To obtain a magnetic information reproducer having high S/N by flowing a pulse current to increase the signal voltage obtained from a magneto- resistance element by >=10 times as high as a normal level to secure a constant current through a bridge circuit as well as to extract the signal voltage component obtained from a signal magnetic field. CONSTITUTION:A feedback loop uses a dummy resistance element 22 as a magneto-resistance element 12 and impresses a DC magnetic field corresponding to the reproduction signal output to the element 22 in order to control the resistance value to an optimum level. A DC component is supplied to a conductor pattern 23 from the output of a sample and hold circuit 19 via an extracting circuit 24 and an amplifier 25. The DC magnetic field impressed to the element 22 is changed to minimize the DC component contained in the reproduction signal output. Then the resistance value of the element 22 changes. Therefore the balance conditions of a bridge circuit 13 can always be maintained by the function of the feedback loop although the resistance value of the element 12 increases due to the wear. Thus it is possible to secure the reproduction signal corresponding to the recorded magnetic information by detecting the voltage change.
